TO ALL WH'OM IT MAY CONCERN:

Be it known that I, ALEXANDER MILLAR, of Edinburgh, Scotland, residingat Roxbury, in the county of Norfolk, and State of Massachusetts,have-invented au Improved Oiler and Filler'gand I do hereby declare thatYthe following, taken in Yconnection with the drawings whichaceompanyand form part of this specification, is a description of my inventionsuicient to enable those skilled in the art to practise it.

The invention relates to the construction of vessels or cans lfor oilingmachinery, iilling lamps, Ste.; and consists in constructing the canwith a false bottoru,'in which is a. valve, and from which leads acylinder'provided with a piston, the space `under the false bottomconstituting a shallow charging-chamber `from which leads the eductionpipe, the piston-rod being connectedto a wire, so that the'piston andoiler maybe operated thereby when'the oiler is not directly held in andoperated by the hand.

The object of my invention is to enable a fixed amount of luid to beejected from the can, so as to avoid danger of overiiowing the vessel tobe filled, and pf wasting the oil, and also to enable shafting and othermechanism to `be readily oiled without necessity of introducing the handand arm into proximity with such mechanism. i

I am aware of the construction of the oiler patented by John King Vonthe 10th of July, 1866, but such patented oiler has several defectswhich are obviated in inyinvention.

The drawing represents a central section of an oiler and fillerembodying my invention.

a denotes the can or vessel to containthe lubricant or other luid; b thebottom lthereof, at a little distance above which is a parallel falsebottom, c, the space between constituting a shallow chamber, d, fromwhich the fluid is ejected through the discharge pipe e, which opensout-.of one side of the chamber, as seen in the drawing. The falsebottom c is provided with a valve, f, whichopens and closesafiluid-passage, g, -leading from the main reservoir h intothecharging-chamber d. Extending up from the chamber d, and openingfreely thereinto, is a cylinder, z', provided with lu. piston", lc, onthe end of a piston-rod, l, which extends vup through the can, and hasat its top a thumb-piece, ni, for operating the piston by hand, ivliileconnected thereto is a wire, n, extending along a long handle, o, madeof suitable length to allow the can to be carried by its means tomechanism beyondthe reach of the artisan, as will be readily understood.'The piston-rod isprovided with a spring, p, for press ing the pistonupto the top of the cylinderLand the piston is preferably made withcup-packing, as seen in the drawing. the mouth a conical strainer, s,which shall prevent any foreign matters (which would clog the ejectingtube) from entering the` reservoir in charging it with fluid.

The operation of thc oiler is as follows: The reservoir being chargedwith oil through the tep q, if the piston c be now pressed down theexpansion oi' the spring will driy'el it up when thc rod lis released,and the uid will rush through the opening g into the chamber d to supplythe vacuum caused by ascent of piston k, the valvef falling away fromthe opening g bythe pressure of thc liquidabovc.v The pistonibeing thenforced down, the fluid willbc pressed up into the discharge tube e. andejected from its point, the valve f' closing and preventing uid frombeing forced back into the reservoir, and` causing ai'ixedfquaptitytobeejectedupon the mechanism to be oiled, or into the vessel to be iilled,in accordance with 'the degree "of descent' of Vthe piston.

Without the false bottom c and shallow chamber d, and the valve f,-vi'twould, not. be jti'racticai 'to 'e`il`ecttl1is,` as

The mouth q of the vessel is covered by a cap, r, in the usual manner,but I prefer to place within the lluid would not be ejected from thetube with certainty,` but would,"lmuch of'it', simply dbw back intoltbecylinder if `the ejecting tube were connected directly to suchcylinderjf l 1 I claim, in combination with the reservoir, ejectingpipe, cylinder, and pistonthe' julseil bottom 2, gslillw` chamber d, andvalvef, constructed and arranged to operate substantially asset forth,
